To a whom it may concernr Be it knownthat I, CHARLES 0. WHEELER,

a citizen of the United States, 'and'a resident of Holland, in the county of Ottawa and State of Michigan, have invented a new and useful Window-Sash,-of which the following is a specification.

My invention relates to window-sashes, one

object being toprovide certain improvements in the'applicati'on, structure, and arrangement of the means for locking the windowsash in different positions, the said changes represented in the accompanying-drawings,

in which i Figure 1 is an inside view of a portion of a window-frame with my improvements applied to the lower window-sash therein. Fig. 2 is a transverse section taken in the plane of the line 2 2 of Fig. 1. tail sectional .view through the top rail of the lower sash and bottom rail of the upper sash at that point where one of the adj ustingscrews is located. Fig. 4 is a detail top plan View of a portionof the same. Fig. 5 is a detail view of a portion of one of the stiles of the lower window-sash, its movable section, and one of the adjusting-screws for operating the movable section, a portion of the protecting-strip which overlaps the movable section being broken away to show the adj ustingsc rew in full lines. Fig. 6 is a transverse section taken in the plane of the line 6 6 of Fig. 5. Fig. 7 is an enlarged detail side View, partially in section, of the adjusting-screw and its attached parts; and Fig. 8 is an end view of the same.

The sill of the windowframe is denoted by A and the sides of the window-frame by a a,

which frame may be of any well-known or approved construction, having the usual vertical grooves or runs for the upper and lower window-sashes B and G. The top rail of the lower sash is denoted by c and the two stiles thereof by 0' 0 The bottom rail of the upper sash B is denoted by b."

Fig. 3 is an enlarged de- The inside outer edge of one'of the lower sash-stilesthe stile c, for example-is cut away to form a seat fora movable section 0 which movable section may be positively moved bodily toward and away from the side a of the window-frame by means of a plurality of adj usting-screws D, in the present instance two of which adjusting-screws are shown, one being located a short distance above the bottom of the sash and the other a short distance below the top of the sash. This movable section and itsadjusting means may be located along both'stiles of the lower sash, or it may be located along one or both stiles of the upper sash, if so desired. The outside upper edge of the top rail'c of the lower sash is similarly cut away to form a seat for a movable section 0 which movable section is positively moved toward and away from the inner face of the lower rail hot the upper sash'by'means' of a plurality of adjustingscrews D, in the presentinstance two of which screws are shown engaging'the movable section at such points at shortdistances from each'sideof its middle portion as will under pressure exerted by said screws produce an outward curving of said movable section 0 when resisted by the rail b. The ends of the movable section 0 extend to the outer edges of the centralvertical parting-strips a a of the window-frame, so as to permit the lower sash to freely slide up and down within its runways without interfering with the inward and outward'bodily movement of the said movable section. V

A'thin protectin'g-stripE, of metal, wood, or other suitable material, is secured along the inner face of the stile c of the lower sash, which strip extends over the inner face of the movable section a and also hides practically all of the shanks of the adj listing-screws D. A similar protecting-strip F is secured along the top of the upperrail c of the lower sash,

which strip F also overlaps the upper face of the movable section 0 and efiectually covers the shanks of the adjusting-screwsD.

The structure and arrangement of the adjusting-screws D, whereby the screw is en-' gaged with the movable section and the sash stile or rail, is as follows: The end of the screw-threaded shank d of the -adjustingscrew is reduced, upon which reduced end is mounted a loose collar (1 and a fixed small 6* difference being that'asthe screws along the washer (1 beyond which small washer the end of the shank is spread or upset for permanently securing the loose collard thereon. Before the collar d is secured in vposition upon the shank a nut d? is engaged with the screw-threaded shank I e The adjusting-screws located along the stile of thesash for moving the movable section e "-bodily toward and away therefrom in the plane of the 'sash are embedded iii the stile and movable section as. near the inner face of the stile as possible, so as to permit the handlesdj of theadjusting-screwsbeing manipulate'd without coming inconta'ct with the windo'w-ip'a'ner Th'e'loose collard" is inserted into a erossslit c in the movable sectiona and the vnut d is embedded intoa cross-soeket o ,,'so that'when the screw D is ,t'u'rned the movable section is positively forced toward 7 and awayfrom the stile e; The nut D is tapped out of center, so as, to bririg its opening nearer the inner face of the stile c of the sash for the purpos'elhereinaboye set forth of bringing the screw farther awayj from the. ivindow-pane'. I l p g f The adjusting -,s'c rew s D; which are. em-Q bedded. in the top raile and the movable secfl tion ief, are quite similar; to the, a ljus'tii r 1 screws located along thesi de stiles, the o'nly top rail are 'tm-n'ea they positively move the movable; section c bodily toward and away from-'the'top 'rail iii adireetion at rightan gles'to the plane of thesash. The?nnts df for the adjusting-screws at the top'ofthelo wer sash need not be tapped out of oentei, as there is no objectin so doing. v I v v Bymeans of the strpct'urehereinabove set i'orth'Ifam enabled when the window is closed Y to fasten both sashes shugly intposition, seas; to prevent'the lower sasli fronibeing raised or the "upper sash from being dropped from; the outside; alsofton ender the window me ticall'y dust-proof and air-tightg and therefore more nearlyweatherproof, also'p'reventing its rattling, pr, lia'ving'opene eithersash to'any point desirable for ventilation, I am enabled to lock either sash securely against i'n'trusioii from outsideor against accidents to'children or careless persons from inside, at the-same time'spreventing its rattling. Also laccomi-j nlish great economy in first labor of fitting lhe sash to the window-frame, for the workman, knowing that-"he can fall back upon the" movable section adjustable to mihor e'rr'ors and.imperfcct'ionsin the window-frame, can,

make the sash to fit'loosely with entire'indif ferenee to changes in' the weather,\vhi'ch'1ater would destroy the nieeties of fit in the ot-(1i; harysash. "h

The movable section e is forcedfby the'adj listing-screws against the side frame it within the runway of the lower sash; The-top niovfiblfi'fiBChlOll of may be forced outwardly by.

thead "ustin -screws sniwl a ainst the inner b, b a i face of the lower rail 1) of the upporsaslu It movable section o 'outwardly against the side a of the window-frame.

It is evident that changes might be resorted to in the form-and arrangement of the sev-e eral parts without departing from the sprrlt' and scope of my invention.,-. l'lence I donot I wish to limit myself strietly to the structure her n t forth; t Ln y Whatlclaim is 4 i.
